YINCHUAN, June 30 (Xinhua) -- China on Monday reached a major milestone in desertification control by completing a barrier belt along the southeastern edge of the Tengger Desert in the northwestern Ningxia Hui Autonomous Region.
In Changliushui village in the city of Zhongwei, workers installed the final row of straw checkerboards, a traditional sand-fixing method, locking the final stretch of shifting dunes in the Ningxia part of the Tengger Desert after a sand control project spanning more than six decades.
